B = (5, 2)
fb(x) = x - x(B) + y(B)
A = (1, 3)
fa(x) = x - x(A) + y(A)
O = Intersect(xAxis, yAxis)
W = Point(fa)
w = Vector(O, W)
Z = Point(fb)
z = Vector(O, Z)
summe: w + z
ZA = Intersect(fa, xAxis)
ZB = Intersect(fb, xAxis)
Sum: (x(W) + x(Z), y(W) + y(Z))
u = Vector(O, ZA)
v = Vector(O, ZB)
e: u + v
